中重度碱化盐土大部分由碱化盐土组成,主要生长大量芦苇等水生植物,由于蒸发量大,使湖泊周边大量盐份蓄积于地表,造成周边生态环境恶化。土壤中多水生生物。中重度碱化盐土主要理化性质指标是:7.0g/kg≥全盐≥4.0g/kg,30%≥碱化度≥20%,8.0≥p H≥7.0。生态恢复主要技术如下:1、深翻晒田+激光平地+深松耕的土地整理技术:造林前一年秋天,深翻晒田,熟化和增加土壤孔隙度,以提高脱盐率。春季造林前,利用激光平地仪平整土
Most of the moderately alkalinized saline soils are composed of alkalized saline soils, mainly growing a large number of aquatic plants such as reeds. Due to the large amount of evaporation, a large amount of salt around the lake accumulates on the surface, resulting in deterioration of the surrounding ecological environment. Aquatic organisms in the soil. The main physical and chemical properties indexes of moderately and heavily alkalized saline soil are: 7.0g / kg≥ whole salt≥4.0g / kg, 30% ≥basicity≥20%, 8.0≥p H≥7.0. The main technologies of ecological restoration are as follows: 1. Deep tillable + laser + deep plowing of land consolidation techniques: the year before reforestation, deep tillable fields, maturation and increase soil porosity in order to improve the rate of desalination. Before spring afforestation, the use of laser flat land leveling instrument
